1 Overview

This User’s Manual provides an overview of the M2401G 24-port 20Gb/s InfiniBand switch for the

Dell M1000e. The switch supports 16 switch ports towards the midplane and 8 external ports. In

addition to supporting passive copper InfiniBand cables, the external ports can provide power for

supporting active cables and optical cables through the use of media adapters.

The switch supports 16 switch ports towards the midplane and 8 external ports. In addition to sup-

porting passive copper InfiniBand cables, the external ports can provide power for supporting

active cables and optical cables through the use of media adapters.

The switch platform comes pre-installed with all necessary firmware, and configured for standard

operation with InfiniBand fabric, and requires an InfiniBand compliant Subnet Manager running

from one of the hosts. All that is required for normal operation is to follow the usual precautions for

installation and connection from the switch to the HCAs or other switches. Once connected, the

Subnet Management software automatically configures and begins utilizing the switch.

Maintenance and configuration of the switch is done in-band over the InfiniBand fabric using the

Mellanox Technologies InfiniBand Administration (IBADM) tools package. This package provides

the ability to upgrade firmware and monitor the temperature, voltage, port utilization, and other sta

tus parameters in the switch.

Basic installation, hot-swapping components and hardware maintenance is covered in “Installa-

tion and Basic Operation” on page 8.

The M2401G switch has a Hot Swap controller and a PSOC Management IC

2 Installation and Basic Operation

2.1 Switch Platform Hardware Overview

Figure 1 shows the front panel view of the switch.

Figure 1: Switch Front Panel and Locking Mechanism

2.1.1 InfiniBand Connectors

InfiniBand connectivity has 8 CX4 microGiGa connectors through the front panel. The remaining

16 interfaces are through the AirMax Midplane Connector out the back of the switch.

Figure 1

shows the front 8 ports.

Each of the front panel connectors has two LEDs located next to the connector. The green LED,

when lit, indicates that the InfiniBand driver is running and a valid physical connection between

nodes exists. The yellow LED when lit, indicates a valid data activity link, this is the logical link.

The yellow LED illuminates when the InfiniBand network is discovered over the physical link. A

valid data activity link without data transfer is designated by a constant yellow LED indication. A

valid data activity link with data transfer is designated by a blinking yellow LED indication. If the

LEDs are not active, either the physical link or the logical link (or both) connections has not been

established.

5. Push the lever on the latching mechanism up, making sure that the latching mechanism catches

the locking bar. The lever should now be parallel to the front panel.

6. Check the indicator lights to make sure the switch has power.

The installer should use a rack cable to support the mechanical and environmental characteristics of

a fully populated switch platform Chassis.

The rack mounting is designed to fit the Dell M1000e Chassis. Take precautions to

guarantee proper ventilation for air intake at the front of the chassis and exhaust at the

rear in order to maintain good airflow at ambient temperature. Cable routing in partic

ular should not impede the air exhaust from the chassis.

2.2.3 Power Connections and Initial Power On

Caution: The switch platform will automatically power up when AC power is applied. There is no

power switch. Immediately upon closing the latching mechanism check to make sure that the

Power on to the Switch LED is lit.

2.2.4 InfiniBand Cable Installation

All cables can be inserted or removed with the unit power on. To insert a cable, press the connector

into the port receptacle until the connector is firmly seated. The GREEN LED indicator below each

port will light when the physical connection is established (that is, when the unit is powered on and

a cable is plugged into the port with a functioning port plugged into the other end of the connector).

After plugging in a cable, lock the connector using the latching mechanism particular to the cable

vendor. The YELLOW LED will light (non blinking indicating that no data is being transferred

yet). When a logical connection is made the yellow LED will blink signifying data is being trans

ferred.

To remove, disengage the locks and slowly pull the connector away from the port receptacle. Both

LED indicators will turn off when the cable is unseated.

Care should be taken not to impede the air exhaust flow through the fan modules.

Note: Cable lengths should be used which allow for routing horizontally around to the side of the

chassis before bending upward or downward in the rack.

2.2.5 InfiniBand Optical Cable Installation

M2401G switches will work with optical cables and media adapters. Insert the media adapter into

the connector and then connect the optical cable to the media adapter. Make sure to close any locks

on the cables and media adapters. The GREEN LED indicator below each port will light when the

physical connection is established (that is, when the unit is powered on and a cable is plugged into

the port with a functioning port plugged into the other end of the connector). The YELLOW LED

will light (non blinking indicating that no data is being transferred yet). When a logical connection

is made the yellow LED will blink signifying data is being transferred.

To remove, disengage the locks and slowly pull the connector away from the port receptacle. Both

LED indicators will turn off when the cable is unseated.

Care should be taken not to impede the air exhaust flow.
